The new Ultegra rear derailleur features Shimano’s Shadow RD design, which gives the derailleur a lower profile and more stable operation.

Everything you need to make your ride distinctively yours: The Shimano Ultegra 2x11-speed Rear Derailleur RD-R8000 SS

The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.

The RD-R8000 rear derailleur creates a reduction in shifting effort at the lever, at the same time remaining sure, quick and precise. The groupset offers two specific rear derailleurs: one for cassettes 11-25 and 11-30 and one for cassettes 11-28 and 11-34, securing a smooth ride in even the highest and steepest mountain areas. Due to the integrated Shadow RD Technology with its race-proven, low profile design, the derailleur is more compact and fits closer to the frame, ensuring less damage in a crash.

Technology

Shimano Shadow RD 
The mechanism rear derailleur, SHIMANO SHADOW RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
